Abstract (en)
Reactive dye mixture contains dye(s) (IA) with a 2,4-difluoro-pyrimidin-6-yl group and dye(s) (IB) with a 4,6-difluoro-pyrimidin-2-yl group, with a chromophore group corresponding to a mono- or disazo dye or metal complex or a 1-amino-4-sulfophenyl-2-sulfo-anthraquinone dye. Reactive dye mixture contains dye(s) of formula (IA) with a 2,4-difluoro-pyrimidin-6-yl group and dye(s) (IB) of formula with a 4,6-difluoro-pyrimidin-2-yl group, with a chromophore group corresponding to a mono- or disazo dye or metal complex or a 1-amino-4-sulfophenyl-2-sulfo-anthraquinone dye: A-XA (IA) A-XB (IB) XA = 2,4-difluoro-pyrimidin-6-yl; XB = 4,6-difluoro-pyrimidin-2-yl; A = a chromophore group. The full definitions are given in the DEFINITIONS (Full Definitions) Field. An Independent claim is also included for a method of dyeing material, especially fibrous material, containing hydroxyl and/or carbonamido groups by applying a mixture of dyes (IA) and (IB) and fixing using heat and/or alkali.
Abstract (de)
Es werden Farbstoffmischungen beschrieben, die einen oder mehrere organische Farbstoffe der unterschiedlichsten Farbstoffklassen mit dem faserreaktiven 2,4-Difluor-pyrimidin-6-yl-Rest und einen oder mehrere organische Farbstoffe der unterschiedlichsten Farbstoffklassen mit dem faserreaktiven 4,6-Difluorpyrimidin-4-yl-Rest enthalten. Die Farbstoffmischungen eignen sich sehr gut zum Färben von hydroxy- und/oder carbonamidgruppenhaltigen Materialien, insbesondere Fasermaterialien, in farbkräftigen Tönen.
